Sportcross 2.0 came with 16" alloys as standard. I've changed mine to 17" from the new IS. I've got spacers on because of the small lug on the front suspension. I know some people file this off. Best to stick with 16" for winter tyres and keep 17" for summer. Here's a before and after..

Brought them off ebay - they'd been refurbed and painted - £360 with tyres but I changed the tyres. As they are 17" they foul the small lug on the suspension arm so I had 5mm spacers fitted. So now I need the mud flaps which I've just ordered thru a dealer. I've got 215 Kumhos on them. I'm pleased with the look,
